    How Much is Onyx Worth?

    The price can vary based on several factors such as quality, size, and color. Generally, a good quality onyx stone can range from $1 to $500 per carat. The price may increase for larger stones or those with unique patterns and colors.

    On the lower end of the spectrum, you can find smaller onyx stones for around $1 to $10 per carat. These are usually more common and may have fewer intricate patterns or less vibrant colors. On the other hand, rare and high-quality onyx stones with exceptional patterns or intense hues can fetch prices ranging from $100 to $500 per carat.

    Quality is crucial in determining the value of an onyx stone. Stones that are free of blemishes, have consistent coloration, and exhibit striking banding patterns command higher prices compared to those with imperfections or inconsistencies.

    Factors Affecting the Value of Onyx

    Iron Impurities

    Onyx with iron impurities tends to have a lower value because these impurities can affect its appearance. When iron is present, it may cause undesirable coloration or streaks in the stone, diminishing its overall aesthetic appeal. As a result, onyx with high levels of iron impurities may not be as sought after and therefore commands a lower price in the market.

    For example, if you come across black onyx that appears to have reddish-brown streaks or patches, this could indicate the presence of iron impurities. This type of onyx might be priced lower compared to pure black onyx without such discoloration.


    The types of onyx also play a significant role in determining its value. For instance, pure black onyx is generally more valuable than other varieties due to its rarity and demand for use in jewelry and ornamental objects. On the other hand, banded or multicolored varieties of onyx may have different values depending on their unique patterns and colors.

    When shopping for or evaluating the worth of an onyx piece, consider whether it is pure black or exhibits banding or multiple colors. Pure black specimens are often highly prized for their sleek and elegant look, while banded or multicolored types may vary in value based on their individual characteristics.

    Onyx is a variety of chalcedony, a type of quartz, known for its distinctive, often parallel banding and rich colors. Here are the characteristics and typical price ranges of different types of onyx:

    1. Black Onyx

    Characteristics: Black onyx is perhaps the most famous and widely used variety. It is known for its deep, glossy black color and can be either solid black or have white bands. Black onyx is often dyed to enhance or even out the color and is popular in jewelry and decorative objects.

    Price: Black onyx is generally affordable, with prices depending on the size and craftsmanship of the piece. Small, unworked pieces can be as low as a few dollars, while larger, polished pieces and jewelry can range from $10 to several hundred dollars, especially if set in precious metals or paired with other gemstones.

    2. Green Onyx

    Characteristics: Green onyx varies in color from light to dark green and may have white or lighter green bands. The color is often enhanced through dyeing. This variety is appreciated for its smooth texture and vibrant color, used in both jewelry and decorative carvings.

    Price: Green onyx is moderately priced, similar to black onyx. The value increases with the intensity of the color and quality of the finish, with jewelry and larger decorative pieces fetching higher prices.

    3. Red Onyx

    Characteristics: Red onyx features a range of red hues, from soft pinks to deep reds, often with white or lighter red bands. Like other onyx types, its color may be enhanced. Red onyx is used in various decorative applications and is valued for its striking appearance.

    Price: Red onyx is generally in the same price range as black and green onyx. Its price depends on the depth of color, clarity of banding, and overall size and cut of the stone.

    4. Blue Onyx

    Characteristics: Blue onyx is less common and can range from light to dark blue, typically with white or lighter blue bands. The blue color is usually achieved through dyeing, as natural blue onyx is rare.

    Price: Due to its rarity and unique color, blue onyx can be slightly more expensive than the more common black or green varieties, especially for natural stones.

    5. Honey Onyx

    Characteristics: Honey onyx has a translucent quality with colors ranging from soft yellows to warm browns. It often exhibits a beautiful, natural banding and is used in high-end interior decor, such as countertops and lighting fixtures, due to its striking appearance when backlit.

    Price: Honey onyx is one of the more expensive varieties of onyx, particularly for large, high-quality slabs used in interior design. Small decorative pieces and jewelry are more affordable but still tend to be priced higher than other onyx types.

    6. Sardonyx

    Characteristics: Sardonyx is a type of onyx that is characterized by its layers of sard (a reddish-brown chalcedony) and onyx (typically black and white bands). This results in a striking, banded appearance with contrasting colors. The bands in sardonyx can be straight, parallel, curved, or in irregular patterns.

    Price: Generally, sardonyx is an affordable gemstone. Smaller, less distinct pieces can be priced at a few dollars, while larger, more striking specimens with clear, sharp banding and rich colors can range from $20 to $100 or more, especially if they are used in well-crafted jewelry pieces.

    The price of onyx varies depending on the color, size, treatment, and whether it is sold as a raw stone, polished piece, or as part of a jewelry or decorative item. Onyx's elegant and versatile appearance makes it a popular choice for a range of applications from fine jewelry to home décor.
